I got another wifi shutdown today, and therefore I'm moving to Fedora 33 with the latest kernel. Please close this issue.
I have also attached the dmesg message below. ** Attachment added: "err.log" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1895449/+attachment/5425911/+files/err.log -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1895449 Title: Internet disconnected unexpectly + Xorg freeze while watching html5 video in Chrome Status in linux package in Ubuntu: In Progress Bug description: A few issues: 1)With Intel(R) Wireless-AC 9560, under kernel 5.4 for Ubuntu 20.04.1, the system sometimes gets disconnected with the network and I get the following error in syslog: iwlwifi: BIOS contains WGDS but no WRDS It is unclear if this is the cause of the problem, but this is likely related to kernel. 2) Watching HTML5 videos on Chrome with Nvidia GPU (440 driver) will sometimes cause xorg freeze.
